ATP-dependent RNA helicase; An ATP-dependent bidirectional RNA helicase with RNA- dependent ATPase activity; does not unwind dsDNA, uses only (d)ATP. Also has ATP-dependent RNA annealing activity; concurrent annealing and helicase activity promote strand-exchange activity. In vitro has low helicase processivity, annealing processivity is probably higher. Required for correct cold adaptation, probably by aiding translation of mRNAs required for photosynthesis and electron transport. Probably regulates the cold-shock-inducible expression of the GroESL chaperones. May partially regulate i [...]

N utilization substance protein; Participates in both transcription termination and antitermination.

Initiation factor IF-2; One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex (By similarity); Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. IF-2 subfamily.

Endoribonuclease YbeY; Single strand-specific metallo-endoribonuclease involved in late-stage 70S ribosome quality control and in maturation of the 3' terminus of the 16S rRNA.

RNA polymerase beta subunit; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.

50S ribosomal protein L3; One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit; Belongs to the universal ribosomal protein uL3 family.

50S ribosomal protein L4; One of the primary rRNA binding proteins, this protein initially binds near the 5'-end of the 23S rRNA. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome.

30S ribosomal protein S4; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit.

Ribonuclease J; An RNase that has 5'-3' exonuclease and possibly endoonuclease activity. Involved in maturation of rRNA and in some organisms also mRNA maturation and/or decay (By similarity). Belongs to the metallo-beta-lactamase superfamily. RNA- metabolizing metallo-beta-lactamase-like family. Bacterial RNase J subfamily.
